operation of automobile service stations. which permits such oil to be delivered directly into waiting vehicles from portable lubricant supply containers, which meters accurately the amount of oil so delivered in each dispensation, which gives effective protection against fraudulent substitution of unauthorized brands or grades of oil and assures freedom from contamination of the oil being dispensed, and which in these and other respects constitutes a more practical and more desirable dispensing system than other systems heretoforeused in service station work. Small portable dispenser carriages are provided," each 0 which mounts a delivery pump, a flow meter, a delivery hose, appropriate oil feed lines, and a liquid'inlet system including means for attaching and sealing portable supply containers on the dispenser and means for opening such con-1 tainers as they are attached to permit discharge of their contents through the dispenser. Provision is made for constantly keeping the delivery hose and feed lines of the dispenser full of oil, for automatically preventing further delivery of oil from the dispenser when a supply container attached to the dispenser inlet system has been emptied, and for automatically restoring the dispenser to operative condition when another full supply container is attached thereto. The arrangement is such that each dispenser and an attached supply container may be lifted and carried readily to various locations and there actuated to deliver accurately metered quantities of lubricant directly into waiting vehicles. The system is further such that the purchaser of the lubricant in each instance is able to observe the amount of oil he receives and to determine whether the oil conforms to the brand and grade ordered. The supply containers used for cooperation with the dispensers may be of comparatively large size, say of five-quart capacity, so that economy may be realized in handling and disdescribed, and also such apparatus including certain modifications or improvements of the apparatus shown in said co-pending application. The. apparatus herein disclosed includes a portable dispensing unit of the character described equipped with a special new liquid inlet system for cooperation with refillable portable supply containers. It also includes new and useful refillable portable supply containers for use with such dispensers. The dispenser unit itself embodies numerous new constructions, arrange-' ments and combinations of parts which improve its design, operation and utility, for instance, by rendering the metering of the lubricant more readily apparent to the purchaser, by indicating clearly the level of lubricant in attached supply container at all times, and by permitting variation in the rate of delivery of lubricant upon manipulation of the pump mounted on the dispenser carriage.

A further feature of the invention is that it provides a dispenser system of the character described which dispenses accurately metered quantities of lubricant directly from refillable portable pensing the oil, and it not only becomes unnecessary to deliver from a number of one-quart containers, or to refill such containers, in the course of dispensing more than a quart of oil, but also short deliveries heretofore resulting from clingage 'supply containers and at the same time gives effective protection to the purchaser of the lubricant against unauthorized substitution of inferior brands orgrades of lubricant by the service station attendant.

These and other features and advantages of our invention and the manner in which they may be attained will become more apparent from the following description of an illustrative embodiment of the invention, when considered in connection with the accompanying drawings in which:

Figure 10.is a longitudinal section through the delivery nozzle of the dispenser.

In the illustrated embodiment the dispenser unit itself is made asa portable carriage which comprises a base l having uprights l2 and I4 projecting vertically therefrom in spaced relation,

preferably with a handle l6 bridging the uprights and attached thereto near their upper ends to allow convenient lifting and movement of the unit. The base Ill-is preferably formed as a casting with appropriate chambers, passages, etc., to accommodate or constitute parts of the dispenser mechanism, the casting being surrounded by a sheet metal skirt 20.

In this form the lower peripheral wall 2| of the casting provides a footing which supports the dispenser in upright position. The upright l2 extending vertically from one end of the base is formed by the barrel 90 of a manually operable pump mechanism hereinafter described. The

in a socket 21 also attached to upright I' l.

Between the uprights l2 and M the base I0 is provided with a liquid inlet system 30 adapted" especially to cooperate with refillable supply contain'ers A having valved liquid outlets 40 on their 'bottom walls. The inlet system 39, for example,

includes a ring-like member 34 defining an inlet throat which snugly receives a tubular outlet spout .42 fixed to the bottom wall of the container A. An outwardly directed flange 36 at the top 'of member 34 is formed with notches 38 (Fig. 5)

held in an annular recess inside of member 34 in position to form a seal with the outside wall of spout 42 when container A is attached to the dispenser.

The container A may have supporting means 45 depending from its lower end to a point below the end of spout 42, to support the container when not attached to a dispenser unit. The skirt 20 of base l9 may extend across the top of the base to a margin 28 defining an opening large enough to receive the container supporting means.

As seen in 1, the spout 42 carries at its lower end an annularseat 46 for a check valve 48 located inside the spout. Valve 48 is normally held against its ,seat by a compression spring 59. As seen in Figs. 1 and 4, a bracket 52 extending to a position below the inlet throat carries a pin 54 which projects vertically to a position such that the end of pin 54 engages valve 48 and lifts it from its seat when container A is attached to the inlet system. It will therefore be apparent that when the spout 42 of the container is moved into the inlet throat defined by member 94, fiuid communication is established between the spout and a small'chamber 69 in the dispenser base; also, that movement of spout 42 into member 94 attaches the container'to the dispenser and forms anair-tight seal between the two by reason of communicates with the dispenser feed lines and receives and passes liquid through the dispenser unit and hose 24 upon operation of the pump mechanism, assuming the dispenser to be in condition for operation. A port 62 in a wall of chamber. leads to a passage 10 which in turn communicates with the lower end of the pump barrel 90. A check valve 63 is normally held across port 62 by a compression spring 64, so as to allow flow of liquid from chamber 60 into passage I0 under pressure but to prevent flow in the opposite direction. Passage 10 also communicates with a passage through a port 12 which is normally closed by a valve 14 under pressure from a spring 16. Passage 80 leads to the lower end of the conduit 22 in upright i4, and as shown in Fig. 1 passage 80 is enlarged between its ends to accommodate a fiow meter 82 positioned there-across;

The meter 82 may be of any known type which will respond accurately to the flow of liquid therethrough. The meter shaft 83 is connected by suitable gearing 9G with an elongated shaft 85 which extends vertically through conduit 22 and connects with a meter indicator 86 mounted on the top of upright l4. The indicator 86 also may be of any known .type suitable for the purpose. It preferably is constructed so as to indicate quarts and tenths of quarts and to give an audible signal when each quart of oil has been metered, as by means of a striker 81' (Fig. 1). It will be noted that the gearing 84 between the meter 82 and the meter indicator shaft 85 is immersed in and constantly lubricated 'by the oil in passage 89.

The discharge of liquid from an attached container A through the dispenser is effected/by manipulation of pump mechanism working in the pump barrel 90 forming upright I2. A piston 9| fits closely inside of barrel 99 and has secured thereto a cylindrical barrel 92, of smaller diameter than barrel 90. Barrel 92 in turn is secured to a tube 93 extending upwardly toward a reciprocable pump handle 94. v A coupling member 95 is provided by which to connect tube 93 with handle 94. In order that the pumping may be effected more easily, or at a slower or more readily controlled rate, a secondary pump mechanism is incorporated with the mechanism just described, this secondary mechanism including a piston 96 fitting inside of the smaller barrel 92 to reciprocate therein and a pump rod 91 connected with piston 96 and extending through tube 93 to a point of direct connection with handle 94. Piston 9| is made hollow so that liquid may enter into barrel 92 therethrough.

' The coupling device 95 is so constructed that the wardly through the notches 98a and then turn-- gage under the flange and thus to hold or lock the container to the dispenser inletsystem.

The small chamber 60 in the dispenser base pump handle 94 may be connected therewith or disconnected therefrom at will, thereby allowing.

the operator of the dispenser to reciprocate all of the movable pump parts and pump from the to accommodate tongues 99 carried by handle a 94, and the'connection of handle 94 with piston 9| is effected by passing the tongues 99 downing the handle so that the tongues engage beneath flange 98. In this condition the handle and the coupling 95 are connected together for simultaneous movement, while when the tongues 99 are disenga ed from the coupling 95, the hendle 94, rod 9'! and piston 96 are freed from connection with Ihe coupling 95 and are movable independently thereof. When so freed, coupling 95 may be moved downward to interengage its lower flange IOI with lug mm on the pump head, thereby holding the primary pump in fixed position during operation of the smaller pump.

The chamber 60 below the liquid inlet system need be large enough only to accommodate a float-controlled valve mechanism located therein; that is to say, chamber 50 is so small that no substantial amount of oil can be dispensed therefrom unless oil is continuously supplied thereinto, as from an attached supply container A. As shown in Fig. 1 and Fig. 7, the-structure defining port 62 presents an upwardly facing valve seat 65, and a valve 66 secured ,to a swinging arm 51 in chamber 60 is adapted to move by gravity onto seat 55 when a float 68, also secured to arm 61, allows such movement. When a container A having oil therein is' attached to the inlet system 30, chamber 60 is full of oil and float 68 holds arm 61 and valve 56 in a position substantially as shown in Fig. 1, thus allowing oil to pass through port 62 in the direction of the pump. When the contents of an attached supply container A have been exhausted, and before the level of liquid in chamber A recedes to port 62, arm 51 drops by gravity and valve 56 as-. sumes a position blocking further flowof liquid from chamber 50 until another supply container I02 to spill out of the inlet, throat. This is avoided by the provision of valve means in passage I 04, which operate to close the passage when a container is removed from the dispenser, together with means for automatically opening such valve means when a supply container is" attached to the dispenser. For example, as shown in Figs. 1, 4, 5 and'fi, a slide IIII having a port III therein is positioned across the passage I04. Slide IIO carries a flap valve 2 which normally lies across port'III so as to prevent the downward flow of oil therethrough. The flap valve has an upstanding finger II3 thereon, and also fingers II4 which limit its swinging movement. In front of finger II3 is a spring pin II5 extending transversely across the passage in a fixed position. A compression spring 6 tends ment of liquid through the two valves upon reversal of the pump pressure, thus equalizing pressure conditions thereon.

When the supply containers A are made of metal or other opaque material their contents are invisible, yet it is desirable that the quality of oil to be dispensed be always apparent to an observer. It is also desirable that the amount of oil in an attached supply container be indicated at all times; otherwise, delays in service might result from failure to keep on the dispenser, or ready for attachment thereto, a supply container holding enough oil for a normal dispensation. According to the illustrated embodiment of our invention, the appearance and approximate quantity of oil in an attached supply container are made apparent at all-times by providing the dispenser itself with a gauge system which shows the liquid to be dispensed and in dicates the level of liquid in the attached container. For example, the upright I4 is provided with an outer, transparent wall I00 which 'is arranged in spaced relation to the feed conduit 22 soas to provide a vertically elongated annular chamber I02 therebetween. Chamber I02 is vented through openings I03 near the top of the upright. At its lower end it communicates with chamber 60 through a passage I04. Itwill be understood that when a supply containerA isv attached to the dispenser, liquid may flow through passage I04 into chamber I02 under the pressure of liquid in the container itself, so that the level of liquid in chamber I02 will correspond to the level of liquid in the attached supply container.

It will be further understood, however, that removal of the supply container before its contents were exhausted might allow liquid from chamber sition in which finger I I3 is free from engagement with pin H5, and in this position the flap valve closes port III and keeps oil from flowing out of the transparent chamber I02. When, however, the slide III) is moved against spring 6, finger II3 engages pin H5, and further movement of the slide results in the pin acting upon finger I13 and swinging the flap valve to substantially the dotted line 'position shown in Fig. 4. This sliding movement of the parts against spring H5 is effected by the action of a reciprocable member I20 which abuts at one end against a lug III depending from slide H0 and which at its other end carries a cam I22 in the path of movement of the supply container outlet spout 42. As seen in Fig. 1, when a supply container A is attached to the dispenser the lower end of its outlet spout 42 engages cam I22 and thus pushes member I20 to the left. Member I20 in turn moves lug III and slide IIO to the leftin opposititon to spring IIB, thereby causing valve II2 to be lifted away from port III and establishing communication between chamber I02 and chamber 50 through passage I04. When the supply container is removed, cam I22 is freed of constraint, so that spring H5 moves slide IIOand member I20 to the right and allows valve I I2 to resume its closed position.

The delivery hose 24 of the dispenser terminates in a valved nozzle 25, which may be of various forms but preferably is constructed substantially as shown in Fig. 10 of the drawings, so as to be automatically operative but at the same time to keep the hose and nozzle full of oil and minimize dripping from the nozzle end. The nozzle body I30 is tubular in shape and at its end is formed with an outlet opening I3l. The end wall defining opening I 3| has an inwardly facing seat I32 for a valve I33. The valve I 33 is secured to the end of a plunger I34 which in turn is connected to a piston I35 movable within a cylindrical portion of the nozzle body. A com pression spring I35 bears against piston I35 and normally holds valve I 33 in closed position. A passage I31 leads from the delivery hose into the nozzle at a point between piston I35 and valve I33, and the cross-sectional area of piston I35 is such'that when pressure is applied to liquid in the nozzle the pressure tends to move the piston against spring I36 so as to unseat the valve,

' Pin I38 is held in a position compressing spring I43 by means of a cam I40 secured to a pivoted liquid from the nozzle, by dripping or otherwise.

except under positive pressure from the pump mechanism hereinabov described.

The illustrated nozzle construction also prevents the admission of air or other fluid into the system through the nozzle opening. This is accomplished by means of a check valve I44 which normally is heldacross a port I45 in a plate'I46 by means of a compression spring I". The valve I44 permits the passage of liquid through port I45 under pressure from the dispenser pump, but it prevents passage of liquid or other fluid through the nozzle in the opposite direction.

Another important feature of the illustrated embodiment,.as shown in Fig. 1, resides in the provision of supply containers A which cooperate with the new portable dispensers substantially as hereinabove described, which are refillable and reusable over and over again, and which at the same time give effective protection against fraudulent substitution of unauthorized brands or grades of oil by. dishonest service station attendants. The illustrated construction prevents unauthorized refilling of the containers lead from the inside of the container into this circuitous passage, and a check valve I55 is provided for each of thes ports so as normally to remain in open position under the force of gravity or of oil flowing downwardly through the ports.

If, however, the container is inverted, or if' an attempt is made to force liquid into the container through the spout 42, then the check valves I55 fall across the ports I54 and prevent entrance of liquid into the container. Furthermore, the partition I5l prevents the insertion of a wire or other tool through the spout 42 so as to move the check valves I55 to open position.

The bottom, side and top walls of the container define a closed chamber into which oil can be introduced only through aspecial filling inlet I64. This inlet is preferably constructed to cooperate only with a special filling nozzle of an authorized oil tank pump, substantially as disclosed in United States Letters Patent No. 1,984,005 of Marvin S. Young. The container A thus is adapted to be refilled only from an authorized tank equipped with such a cooperating filling nozzle and containing an authorized brand and grade of oil.

An indicating device "0, having afloat I12 depending into the container A, may be provided on the container top wall to show when the container has been completely filled. This device, however, does not permit fillingof the container therethrough. I

The apparatus herein described is prepared for operation by attaching a full supply container to the inlet system 30, or otherwise supplying oil into chamber 50, and manipulating the pump 5 handle 04 until all air has been discharged from inlet system, whereupon the entire unit with the supply container thereon may be carried to any desired location for the delivery of an ordered amount of oil. The act of attaching the container to the dispenser opens the container valve 44 and the level gauge valve H2 and causes oil to fill chamber 60, whereupon fioat 68 rises and opens valve 58. To dispense a desiredamount of oil into the crankcase of an automobile, the dispenser nozzle 25 is placed in the crank case filler pipe, with the trigger I4 I turned to free pin I 38, and the pump handle 94 is reciprocated until the desired amount of oil has been dispensed. Each increment of oil passing through the dispenser is registered by the meter 82 and recorded on the meter gauge 86. The pumping rate may be increased by connecting the pump handle 94 with coupling 95, or decreased by disconnecting the handle from coupling 95 so that only the smaller. pump piston 96 is operative. As soon as the desired amount of oil has been recorded on the meter gauge, operation of the pump is discontinued, and fiow of oil from the nozzle 25 immediately ceases. The nozzle may then be replaced in the socket 21, and the unit may be carried to another location for another dispensing opera-' tion.

The meter gauge 88 always can be seen by both the service station attendant and the purchaser of the oil. The appearance of the oil is evident from a glance through the transparent wall I40,

- as well as the level of oil in the attached container. When this level becomes low, or at any other time, the attached container can be removed, refilled and replaced or substituted by another full supply container, without in any manner afiecting the accuracy of the dispensing operations. If the dispenser .pump is operated until an attached container has been completely emptied, this condition is evidenced immediately by inability to continue manipulation of the pump; for when an attached container has been emptied the float 58 drops to a position where valve 56 closes port 62 and prevents further passage of oil therethrough under pump suction. It is then necessary only to'remove the emptied placed at any desired location for a dispensing operation, and they are independent of bulky supply containers-hence their practicability for service station operations. In addition, effective protection is provided against unauthorized substitution of inferior brands or grades of oil, because boththe supply containers and the oil being dispensed are visible to purchasers; the containers are adapted to be refilled only in accordance with M an authorized system; and the dispensers cannot be operated except when cooperating supply'containers holding oil are attached thereto.

Although we have illustrated and described n'umerous'new features and details of construction and operation in reference to a particular embodiment of our inventiomit will be understood that various changes, additions, alterations and omissions can be made in other embodiments while still utilizing new and useful contributions of our disclosure. We therefore desire that our invention be accorded a scope fully commensurate with its novel contributions to the art, as limited only by the fair requirements of the appended claims. I
